Trisections of non-orientable 4-manifolds
Maggie Miller, Patrick Naylor
We study trisections of smooth, compact non-orientable 4-manifolds, and introduce trisections of non-orientable 4-manifolds with boundary. In particular, we prove a non-orientable…

Multisections of 4-manifolds
Gabriel Islambouli, Patrick Naylor
We introduce multisections of smooth, closed 4-manifolds, which generalize trisections to decompositions with more than three pieces. This decomposition describes an arbitrary smoo…
